How are postural strategies modified along the time?

Postural control is critical for effective performance of all goal-directed activities. For maintenance of postural equilibrium against gravity and environmental disturbances, central nervous system produces centrally organized patterns of muscle activity based on initial conditions, perturbation characteristics, learning and intention. These organized strategies are called "postural strategies...
